Participants

Reaction Steps

Indan-1-one (3.30 g), thiophene-3-carboxaldehyde (2.60 ml), acetic acid (0.47 ml) and piperidine (0.57 ml) were heated together on a steam-bath for 16 hours. The mixture was cooled to give a solid mass which was boiled with IMS (120 ml) and hot filtered to remove insoluble material. The filtrate was cooled in ice to precipitate a brown solid which was collected by filtration and dried to give 2-(3-thienyl)methyleneindan-1-one, m.p. 137-13 8° C.
